The uncinate process can be attached to either the lateral nasal wall, on the lamina papyracea (50%), the anterior cranial fossa, on the ethmoidal roof (25%), or the middle concha (25%). The superior attachment of the uncinate process determines the drainage pattern of the frontal sinus.
In anatomy, a process (Latin: processus) is a projection or outgrowth of tissue from a larger body. [1] For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes). [2]
Uncinate process of ethmoid bone, a process located in the nasal cavity; Uncinate process of vertebra, a hook-shaped process on the lateral borders (side edges) of the superior (top) surface of the vertebral bodies of the third to the seventh cervical vertebrae; Uncinate process of pancreas, a small projection from the pancreas
The uncinate process is a small part of the pancreas. The uncinate process is the formed prolongation of the angle of junction of the lower and left lateral borders in the head of the pancreas . The word "uncinate" comes from the Latin "uncinatus", meaning "hooked".
Uncinate, meaning "hooked," can have several meanings in anatomy. Uncinate process of pancreas; Uncinate process of ethmoid bone, close to nasal sinus
Above the attachment of each greater wing is a broad groove, curved something like the italic letter f; it lodges the internal carotid artery and the cavernous sinus, and is named the carotid sulcus. Along the posterior part of the lateral margin of this groove, in the angle between the body and greater wing, is a ridge of bone, called the ...
Behind the lacrimal process of the inferior nasal conchae lies a broad, thin plate, the ethmoidal process, which ascends to join the uncinate process of the ethmoid; from its lower border a thin lamina, the maxillary process, curves downward and lateralward; it articulates with the maxilla and forms a part of the medial wall of the maxillary sinus.
The uncinate process has also been reported in Sphenodon and fossil vertebrates including Caudipteryx, oviraptorids, dromaeosaurids, [7] [8] Confuciusornis, Chaoyangia, and Longipteryx; however it apparently does not occur in Archaeopteryx, [6] though Codd et al. (2007) reported uncinate processes in Archaeopteryx. [7]
